I have a couple of questions.
First off, I understand that 4 wheel disc brakes provide better stopping power, and that they also can look pretty trick, especially on a vehicle that didn't originally come with them from the factory. The first question that I have is, how much more stopping power do they provide, as compared to the factory disc/drum setup that's in good condition? I've seen and read about improvements that can be done to the factory rear drum brakes, including using all primary brake shoes, and wheel cylinders with larger bore pistons (S10 wheel cylinders). With the possible problems that can arise with trying to retrofit disc brakes on the rear of these cars (caliper interferance, park brake type and installation), how advantageous is it to convert to disc brakes on the rear? Is it really worthwhile?
Now I know that this question has probably been asked before, but secondly, is there any kind of writeup that shows a complete overview of a 4 wheel disc brake conversion on these cars, including the compatibility of the original hydraulic system (stock master cylinder, stock proportioning valve), with a 4 wheel disc brake setup?
The way I see it, you can overcome the mechanical issues (caliper fitment, park brake, wheel clearance) of a 4 wheel disc brake conversion, but you still need a hydraulic system, that's going to operate the front and rear brakes with the proper balance, and without causing brake lockup issues.
Just sayin'.
